Description

机动车辆的底盘Chassis of motor vehicles

技术领域technical field

本发明涉及一种如权利要求1前序部分所述的机动车辆的底盘。The invention relates to a chassis of a motor vehicle according to the preamble of claim 1 .

背景技术Background technique

机动车辆的底盘具有一个前桥和一个后桥，其中，一个第一稳定器在前桥区域内延伸，该第一稳定器在端部处连接在用于前桥前轮的车轮悬架上。一个第二稳定器在后桥区域内延伸，该第二稳定器在端部处连接在用于后桥后轮的车轮悬架上。The chassis of the motor vehicle has a front axle and a rear axle, wherein a first stabilizer extends in the region of the front axle, the first stabilizer being connected at the end to a wheel suspension for the front wheels of the front axle. A second stabilizer extends in the area of the rear axle and is connected at the end to the wheel suspension for the rear wheels of the rear axle.

在实践中已知的底盘中，每个车轮悬架配属有一个弹簧减震系统，这个弹簧减震系统一方面支撑在车轮悬架上，另一方面支撑在机动车辆车身上。弹簧减震系统的弹簧元件又称结构弹簧。In chassis known from practice, each wheel suspension is assigned a spring damping system which is supported on the one hand on the wheel suspension and on the other hand on the motor vehicle body. The spring elements of the spring damping system are also called structural springs.

此外，从实践中已知，每个稳定器的每个端部，即稳定器在前桥区域的端部以及稳定器在后桥区域的端部，都各配属有一个液压调节元件，通过这个液压调节元件可以在相应的稳定器的相应端部施加力和/或力矩以实现主动式摆动抑制(Wankstabilisierung)。Furthermore, it is known from practice that each end of each stabilizer, ie the end of the stabilizer in the area of the front axle and the end of the stabilizer in the area of the rear axle, is assigned a hydraulic adjustment element, by means of which The hydrostatic adjustment elements can exert forces and/or torques on the respective ends of the respective stabilizers in order to achieve active roll damping.

发明内容Contents of the invention

在此基础上，本发明的目的是提供一种新型的机动车辆的底盘。用以达成上述目的的解决方案为一种如权利要求1所述的机动车辆的底盘。根据本发明，每个稳定器均固定连接于该机动车辆的车身，使得相应的稳定器不会发生相对于该车身的自由旋转。On this basis, the object of the present invention is to provide a new type of chassis for a motor vehicle. The solution to achieve the above object is a chassis of a motor vehicle as claimed in claim 1 . According to the invention, each stabilizer is fixedly connected to the body of the motor vehicle such that free rotation of the respective stabilizer relative to the body does not occur.

由于这些稳定器固定连接于机动车辆车身而且相应的稳定器不再能相对于车身自由旋转，所以可以借助起主动式摆动抑制作用的液压调节元件来实现升降功能。Since the stabilizers are fixedly connected to the body of the motor vehicle and the respective stabilizer is no longer freely rotatable relative to the body, the lifting function can be implemented by means of hydraulic adjustment elements which act as active roll dampers.

本发明优选、但绝不强制使用液压调节元件。也可以设想，用例如电力调节元件代替液压调节元件，或者作为液压调节元件的补充。此外可设想的是，所述稳定器也可以是一般类型的辅助弹簧，也就是说，所述稳定器不一定必须是连接在中间的扭转杆

Figure BSA00000832276800021
The invention prefers, but by no means mandates, the use of hydraulic adjustment elements. It is also conceivable, for example, to replace the hydraulic adjusting element with an electric adjusting element, or to supplement the hydraulic adjusting element. Furthermore, it is conceivable that the stabilizer can also be an auxiliary spring of the general type, that is to say that the stabilizer does not necessarily have to be a torsion bar connected in the middle
Figure BSA00000832276800021

据此，在现有技术中起主动式摆动抑制作用的作为示例的液压调节元件，根据本发明可以用来实现其他功能，即保证升降功能，以便相对于底盘的结构弹簧抬升或降低机动车辆车身。Accordingly, the hydrostatic adjustment element, as an example, which in the prior art acts as an active roll damper, can be used according to the invention to perform a further function, namely to ensure a lifting function for raising or lowering the motor vehicle body relative to the structural springs of the chassis .

在此情况下，如果以第一作用方向对配属于相应稳定器端部的液压调节元件进行同向控制，就能实现机动车辆车身相对于弹簧减震系统的结构弹簧的抬升。如果以第二作用方向对配属于相应稳定器端部的液压调节元件进行同向控制，就能实现机动车辆车身相对于弹簧减震系统的结构弹簧的降低。如果对配属于相应稳定器端部的液压调节元件进行方向相反的控制，就能实现主动式的摆动抑制。通过以上述方式对液压调节元件进行控制，可以实现机动车辆车身的抬升、机动车辆车身的降低以及主动式的摆动抑制。In this case, lifting of the motor vehicle body relative to the structural springs of the spring damper system can be achieved if the hydraulic adjustment elements associated with the respective stabilizer end are actuated in the same direction in the first direction of action. Lowering of the motor vehicle body relative to the structural springs of the spring damper system can be achieved if the hydraulic adjustment elements associated with the respective stabilizer end are actuated in the same direction in the second direction of action. Active roll damping can be achieved if the hydraulic adjustment elements associated with the respective stabilizer end are actuated in opposite directions. By controlling the hydrostatic adjustment element in the above-described manner, it is possible to raise the motor vehicle body, lower the motor vehicle body, and actively suppress roll.

优选地，每个液压调节元件均与一个弹簧元件串联连接，该弹簧元件由相应的稳定器的一个区段构成，其中，由液压调节元件和稳定器所提供的弹簧元件构成的这个串联连接与弹簧减震系统并联地连接在相应的车轮悬架和机动车辆车身之间。Preferably, each hydraulic adjustment element is connected in series with a spring element formed by a section of the corresponding stabilizer, wherein this series connection of the hydraulic adjustment element and the spring element provided by the stabilizer is connected with The spring damping system is connected in parallel between the corresponding wheel suspension and the body of the motor vehicle.

A hydraulic adjusting force and/or a hydraulic adjusting torque can be applied to the respective end of the respective stabilizer 18 , 19 via the hydraulic adjusting element 23 in order to achieve an active roll damping of the motor vehicle 10 . Such active roll damping by means of hydraulic adjustment elements 23 engaging at the ends of the stabilizers 18 and 19 is known in principle from the prior art and will therefore not be described in detail here. It should only be pointed out here that each hydraulic adjustment element 23 can comprise a hydraulic adjustment cylinder 24 to which hydraulic pressure can be applied by means of a hydraulic pump 26 driven by an electric motor 25 .

在本发明范围内，稳定器18和19固定连接于机动车辆10的车身12，使得稳定器18、19不能发生相对于车身12的自由旋转。图1通过稳定器18和19与机动车辆10的车身12之间的连接线对此进行了大幅度的简化示意，其中如图1所示，每个稳定器18、19均优选在其中段固定连接于机动车辆10的车身12。Within the scope of the invention, the stabilizers 18 and 19 are fixedly connected to the body 12 of the motor vehicle 10 such that free rotation of the stabilizers 18 , 19 relative to the body 12 cannot take place. This is shown in a greatly simplified illustration in FIG. 1 by the connecting lines between the stabilizers 18 and 19 and the body 12 of the motor vehicle 10, wherein as shown in FIG. 1 each stabilizer 18, 19 is preferably fixed in its middle section Attached to the body 12 of the motor vehicle 10 .

通过稳定器18和19在机动车辆的车身12上的这种固定连接，每个液压调节元件23均与一个弹簧元件27串联连接，这个弹簧元件由相应的稳定器18或19的一个区段构成。这个由液压调节元件23与稳定器18或19所提供的弹簧元件27构成的串联连接在每个车轮悬架17区域内与相应的弹簧减震系统20并联连接在车轮悬架17和机动车辆10的车身12之间。Through this fixed connection of the stabilizers 18 and 19 on the body 12 of the motor vehicle, each hydrostatic adjustment element 23 is connected in series with a spring element 27 formed by a section of the respective stabilizer 18 or 19 . This series connection consisting of the hydraulic adjustment element 23 and the spring element 27 provided by the stabilizer 18 or 19 is connected in parallel with the corresponding spring damping system 20 in the area of each wheel suspension 17 between the wheel suspension 17 and the motor vehicle 10.
