Suspension device applied to medium and heavy duty truck cab

Abstract

The invention discloses a suspension device applied to a truck cab and relates to a suspension device applied to a medium and heavy duty truck cab. The suspension device comprises a front suspension device and a back suspension device matched with the front suspension device to be used. The suspension device is characterized in that the back suspension device comprises two suspension assemblies in the same structure and a back suspension cross beam (1) connected with the two suspension assemblies, and a locking warning device is also arranged on the back suspension assemblies. The suspension device has the advantages that the structure is simple, in addition, the cost is low, and the locking warning can also be realized on the suspension deice, so the locking condition of the suspension device can be accurately reflected to drivers, and the occurrence of serious accidents that vehicles can forwards tilt because the cab is not locked in the running process can be prevented. Therefore, the suspension device is suitable for being popularized and used.

Description

technical field [0001] The invention relates to a suspension device for a cab of an automobile, in particular to a suspension device applied to a cab of a medium and heavy-duty automobile. Background technique [0002] The safe driving of the car and road safety are basically controlled by the driver, and the driver's working environment is limited to the cab, so the stability of the cab plays a vital role in the safe driving of the driver. At present, most of the suspension devices used for the cabs of medium and heavy vehicles on the market are full-floating devices, which include supporting the use of front suspension and rear suspension. The upper bracket that is fixedly connected to the front suspension and the cab is made of multiple pieces of sheet metal through welding. Because there are too many welding parts on the upper bracket, the processing procedure is increased, which increases the processing cost, and it is not easy to control the accuracy. The top of the s...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the current suspension device used in the cab of a medium-heavy vehicle is not equipped with a locking alarm mechanism, and the entire suspension device cannot be locked, nor can it accurately reflect the locking of the suspension device to the driver. Therefore, it is impossible to prevent the vicious accident of the cab turning forward during the driving process of the vehicle, which brings great hidden dangers to safe driving. To provide a device that is not only simple in structure, but also low in cost, and can also lock the suspension device It can accurately reflect the locking situation of the suspension device to the driver, so it can prevent the vicious accident of the cab turning forward when the vehicle is running. The suspension device applied to the cab of medium and heavy vehicles
