Power assembly suspended torsion bar and mounting structure thereof

Abstract

The invention discloses a power assembly suspended torsion bar. The power assembly suspended torsion bar comprises a first part (1) and a second part (2) used for being connected with a power assembly. The first part (1) is detachably connected with the second part (2). The first part (1) comprises a first connection arm (11), a first inner core body (12), an outer sleeve (14) and a first damping piece (13) arranged between the first inner core body (12) and the outer sleeve (14). An inserting opening (141) is formed in the peripheral wall of the outer sleeve (14), and the first connection arm (11) extends into the outer sleeve (14) from the inserting opening (141) and is fixedly connected with the first inner core body (12) in the outer sleeve (14) or integrated with the first inner core body (12) in the outer sleeve (14). The power assembly suspended torsion bar is of a split structure so as to be conveniently mounted and dismounted or maintained, and is small in size, and low in weight, and after the power assembly suspended torsion bar is mounted, the mounting space can be reduced.

Description

technical field [0001] The invention relates to a suspension torsion bar, in particular to a power assembly suspension torsion bar and its installation structure for motor vehicles. Background technique [0002] Typically, in order to support the powertrain of a motor vehicle, its suspension system employs multiple suspension components. These components isolate the vibration transmission between the powertrain and the powertrain bearing parts (such as the body or subframe, etc.) through elastic elements, thereby improving the safety and comfort of the vehicle. In particular, when the engine is arranged laterally, a suspension torsion bar should also be used to reduce the transmission of vibration, otherwise the members of the vehicle will obviously feel the vibration transmitted to the vehicle body due to the operation of the engine. [0003] in such as figure 1 In the common suspension torsion bar shown, the two ends of the lever arm of the suspension torsion bar are res...

AI Technical Summary

Problems solved by technology

And when this kind of suspension torsion bar is installed, because the first inner core body 12 is fixedly connected with the powertrain carrier, and the outer sleeve 14 transmits vibration, the support for supporting the outer sleeve 14 on the powertrain carrier cartridge (see figure 2 The diameter of the supporting cylinder 5) is relatively large, so that the outer sleeve 14 has enough radial movable space in the supporting cylinder, so that the required installation structure space is relatively large
