Abstract

The invention discloses a connecting device for a cab and a car frame. The connecting device comprises a first mounting frame, a spring shock absorber, a second mounting frame and a mounting barrel. Avertically arranged spring shock absorber is in clearance fit with the mounting barrel, the spring shock absorber and the mounting barrel can relatively move up and down, the top of the spring shockabsorber is fixedly connected to the floor metal plate of the cab through the first mounting bracket, and the mounting barrel is fixedly connected with the car frame through the second mounting bracket, so the relative movement of the cab in the Y direction (horizontal right-to-left direction) of the car frame is limited so as to ensure the stability of the support in this direction. Meanwhile thespring shock absorber and the mounting barrel can relatively move up and down so that the connecting device achieves upper and lower vibration-reducing movement of the cab relative to the car frame.The connecting device has simple structure and small occupied space, and does not interfere with the arrangement of other components, so the overall weight and cost of the car can be effectively controlled.

Description

technical field [0001] The invention relates to the field of automobile suspension systems, in particular to a connection device between a cab and a vehicle frame. Background technique [0002] For trucks with non-load-bearing body structure, the cab suspension system is an important part, which is used to fix the cab and the frame to support the cab; in addition to the chassis suspension system, the driver The secondary vibration reduction system composed of the cab suspension system can also attenuate the vibration of the cab caused by the excitation of the road surface during the driving process of the vehicle, improve the driving comfort of the occupants, and effectively increase the fatigue life of the cab structure. [0003] At present, when domestic trucks are used in the actual application of the rear suspension position of the cab, spring shock absorbers are arranged and installed. Mounting brackets are respectively arranged on the sides, and the bolts are passed t...
