Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 , figure 2 As shown, this embodiment provides a two-way damping cab rear suspension device, which includes a left rear support assembly, a right rear support assembly, and a gantry frame, and the structure of the left rear support assembly and the right rear support assembly Same, symmetrically arranged on the gantry, the left rear support assembly and the right rear support assembly both include longitudinal shock absorbers and transverse guide assemblies. The lower end of the longitudinal shock absorber is hinged to the gantry frame, one end of the transverse guide assembly is rotatably connected to the longitudinal shock absorber, and the other end is rotatably connected to the gantry frame.

[0017] The longitudinal shock absorber includes an upper bracket 1, a hydraulic lock 2, a middle connecting bracket 3, and...

Abstract

The invention discloses a two-way damping type cab rear suspension device. The two-way damping type cab rear suspension device comprises a left rear supporting assembly, a right rear supporting assembly, a left rear guide assembly, a right rear guide assembly and a portal frame, all of which are laterally symmetric. The left rear supporting assembly is connected with the portal frame through the left rear guide assembly and comprises an upper support, a hydraulic lock, a middle connecting frame and an air spring damper assembly. The left rear guide assembly comprises a guide pull rod and a transverse damper, and a rubber lining is arranged in the guide pull rod. Due to the fact that the rubber lining is arranged in the guide pull rod, the interference caused by the guide pull rod in the vertical movement of a cab is eliminated; meanwhile, the guide pull rod can guarantee that cab is automatically reset, lateral vibration can be effectively attenuated through the transverse damper; and by the adoption of the design, the taking comfort and safety of the cab are effectively improved.

Description

technical field [0001] The invention relates to a two-way damping cab rear suspension device. Background technique [0002] The rear suspension of the cab can attenuate the vibration transmitted from the road to the cab. At present, the guide components generally use side tie rods or side shock absorbers. [0003] In the Chinese utility model patent with the authorized announcement number CN20434123U, an integrated cab rear suspension assembly is disclosed, which includes a pair of rear suspension lower supports respectively fixed on the left and right longitudinal beams of the vehicle frame, two rear suspension The top of the lower support is obliquely fixed with a supporting beam plate; the adjacent sides of the tops of the two supporting beam plates are connected by a beam assembly, and the opposite side of the top of the two supporting beam plates is fixed with a side To the pull arm assembly, the connection between the lateral pull arm assembly and the supporting beam ...
