Powertrain suspension torsion bar and its mounting structure

Abstract

The invention discloses a power assembly suspension torsion bar, which comprises a first part (1) and a second part (2) used for connecting the power assembly, the first part (1) and the second part (2) are detachable The first part (1) includes a first connecting arm (11), a first inner core (12), an outer sleeve (14) and the first inner core (12) and outer sleeve (14 ), a socket (141) is provided on the peripheral wall of the outer sleeve (14), and the first connecting arm (11) extends into the socket (141) The outer sleeve (14) is fixedly connected with the first inner core (12) in the outer sleeve (14) or formed as an integral structure. The powertrain suspension torsion bar according to the present invention has a split structure, which is convenient for installation, disassembly or maintenance, and is smaller in size and lighter in weight. After installation, the powertrain suspension torsion bar can also reduce the installation space.

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...

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
