Truck cab lift system suspension and lock release control cable automatic controller

Abstract

Truck cab lift system suspension and lock bolt unlocking control cable automatic controller, electric cylinder lifting chain plate (7) and electric cylinder upper base (8) hinged end is in contact with cab (9), suspension control is, unlocking The spring holder (2) is disengaged from the suspension limit plate (28) without contact, the elastic force of the slider compression spring (13) pushes the slider (12) to move to the right to the suspension closed position, and the slider (12) restricts the chain The plate (7) rotates; the lock bolt unlocking control is that the elastic force of the unlocking spring (3) pushes the unlocking spring limit rod (4) up a certain distance, and the unlocking spring limit rod (4) pushes the B end of the long control cable wire (5). ) goes up, the end A (22) of the long control cable wire overcomes the torsional force of the torsion spring (18) of the unlocking hook and pulls the unlocking hook (17) into contact with the unlocking hook limit post (34), and the unlocking hook limit post (34) stops the Hold the elastic force of the unlocking spring (3) to push the unlocking spring limit rod (4) upward, and the lock bolt is unlocked.

Description

technical field [0001] The invention relates to an automatic control device for suspension and lock bolt unlocking, in particular to an automatic control device capable of controlling the suspension of a truck cab lift system and the lock bolt unlocking. Background technique [0002] At present, the known lock unlocking control of the truck cab lifting system is a hydraulic cylinder unlocker, which is composed of an electric pump, a control valve, an oil pipe, an oil cylinder, a wiring harness, etc. The realization of the truck cab lock unlocking is achieved by : The wiring harness connects the electric pump with the car battery, which can control the operation of the electric pump. The control valve controls the high-pressure oil to enter the oil cylinder through the oil pipe. The piston rod of the oil cylinder can make a reciprocating linear motion to push the lock bolt of the truck cab to unlock or lock, but the above unlocker The structure is complex, the manufacturing c...

[0002] At present, the known unlocking control of the locking bolt of the truck cab lifting system is a hydraulic cylinder unlocking device. The hydraulic cylinder unlocking device is composed of an electric pump, a control valve, an oil pipe, an oil cylinder, and a wiring harness. : The wire harness connects the electric pump with the car battery, which can control the work of the electric pump. The control valve controls the high-pressure oil to enter the oil cylinder through the oil pipe. The structure is complex, the manufacturing cost is high, the work fails at minus 35 degrees, oil leaks, and pollutes the environment;

[0003] Equally, the known suspension controller of truck cab lifting system is a hydraulic cylinder type suspension controller and an external shackle type suspension controller, and the hydraulic cylinder type suspension controller is composed of hydraulic valves, oil pipes, oil cylinders, etc. The realization of the suspension control of the room lifting system is: the hydraulic valve controls the oil circuit in the hydraulic cylinder through the oil pipe, so that the piston rod of the hydraulic cylinder has the free movement stroke required by the suspension stroke to realize the suspension control; the external hook ring type suspension control The device is composed of chain plates, shackles, limiters, etc.; the suspension control of the truck cab lifting system is realized by: the two ends of the chain plate are respectively hinged with the cab and the lift cylinder, and the other end of the lift cylinder is connected with the truck. The frame is hinged, and the cab and the frame are hinged to form a four-bar mechanism to realize the suspension function. When the cab is lifted to a certain angle, the hook ring hooks the limiter to realize the suspension control; however, the structure of the hydraulic cylinder suspension controller is complicated. , high manufacturing cost, high resistance force, failure to work at minus 35 degrees, oil leakage, polluting the environment, external hook-type suspension controller, can not realize the large-angle turning function of the cab
