Cab turnover control system and cab

Abstract

The invention discloses a cab turnover control system and a cab. The cab turnover control system comprises a liquid control valve, a front protective device, a hydraulic jacking module, an oil supplymodule and a circuit control module, wherein the liquid control valve comprises an access station and an open circuit station, and an ejector rod is arranged on the liquid control valve. A cam is arranged on the front protective device, and the cam is connected with the ejector rod in an abutting mode. The hydraulic jacking module is used for jacking the cab. The oil supply module is used for providing hydraulic oil for the hydraulic jacking module. The circuit control module is used for controlling the oil supply module to start oil supplying or stop oil supplying, the circuit control modulecomprises a first switch, and the first switch is connected with the cam in a contacting mode. According to the cab turnover control system and the cab, through the cooperation of the liquid control valve and the cam, the cab cannot be turned over when the front protective device is not turned over and open, while the cab can be turned over when the front protective device is open, and thus the interference and collision between the cab and the front protective device in the turnover process is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a cab turning control system and a cab. Background technique [0002] Trucks generally need to be equipped with a front protective device to protect the front wall of the truck. For some flat-top trucks, the engine is generally arranged under the cab, and the cab is often turned up during maintenance and maintenance. At present, most of the medium-sized and heavy-duty trucks on the market adopt the hydraulic turning system. Generally, the hydraulic turning system has two modes of manual turning and electric turning. When the electro-hydraulic turning mode is used, the cab will be turned up quickly. [0003] If the truck with a reversible cab adopts a hydraulic tilting system and is equipped with a front protection device, if the operator does not open the front protection before turning up the cab, if the operator directly operates the hydraulic tilting system to lift the ca...

Problems solved by technology

At present, most medium-sized and heavy-duty trucks on the market adopt hydraulic overturning system. Generally, hydraulic overturning system has two modes of manual overturning and electric overturning. When the electro-hydraulic overturning mode is used, the cab will be turned up quickly

[0003] If the truck with a reversible cab adopts a hydraulic tilting system and is equipped with a front protection device, if the operator does not open the front protection before turning up the cab, if the operator directly operates the hydraulic tilting system to lift the cab, it will cause Collision between the front wall of the cab and the front protective device, resulting in severe damage or even scrapping of the cab
