Description
Technical Field
The utility model relates to a vehicle spare part technical field, concretely relates to novel axle differential lock cylinder.
Background
When a vehicle runs on a road section with a large road surface adhesion coefficient on one side and a small road surface adhesion coefficient on the other side, wheels running on the road surface with the low adhesion coefficient skid, the driving force of the vehicle is reduced at the moment, and the vehicle is difficult to pass through the road section.
The existing differential lock device conducts signals by matching a piston and a pressure switch, a piston connecting hole is formed in one side of a cylinder of the differential lock, a switch mounting hole is formed in the other side of the cylinder of the differential lock, the piston connecting hole is communicated with the switch mounting hole, the pressure switch is in threaded connection with the mounting hole, and the differential lock device is arranged so as to have the following problems: 1. the switch mounting hole is communicated with the piston connecting hole, so that the overall sealing performance of the cylinder of the differential lock is reduced, the air leakage phenomenon can occur after the differential lock is used for a long time, and the piston cannot be normally used, so that the differential signal lamp breaks down, and the judgment of a driver is influenced; 2. the piston is provided with a return spring, and the return spring can generate the conditions of spring force attenuation and deformation in the use process, so that the stroke of the piston is changed, and the differential lock fails; 3. one end of the pressure switch is exposed outside the cylinder of the differential lock and contacts with the outside, and when a vehicle runs in the poor road condition process, the pressure switch is easily damaged.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide a novel axle differential lock cylinder, reinforcing gas tightness, increase of service life, reduction fault rate.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel axle differential lock cylinder, includes the cylinder block, the cross section of cylinder block is the trilateral, its characterized in that: the cylinder body comprises a first side face, a second side face, a third side face, a bottom face and an end face, wherein the first side face of the cylinder body is provided with an air inlet, the bottom face of the cylinder body is provided with an air inlet groove communicated with the air inlet, the end face of the cylinder body is provided with an installation through hole, any side face of the cylinder body except the first side face is provided with an installation boss, and an installation cavity for installing a magnetic induction displacement sensor is arranged in the installation boss.
The utility model has the characteristics as above: a non-contact information acquisition mode of a magnetic induction displacement sensor is used for replacing a contact pressure switch, so that the condition that the differential lock pressure switch is damaged to cause air leakage and deformation of a return spring to cause failure is avoided, and the failure rate of a cylinder of the differential lock is reduced; install magnetic induction displacement sensor in the installation cavity of installation boss, replaced the switch mounting hole and the piston connecting hole that switch on, improved the leakproofness of differential lock cylinder, avoid simultaneously because of the damage that magnetic induction displacement sensor exposes and leads to, the life of extension differential lock cylinder.
The utility model discloses further setting is: the mounting through holes are respectively formed in three top points of the end face of the cylinder body, and first grooves are formed in the end face of the cylinder body corresponding to the mounting through holes.
The utility model has the characteristics as above: connecting bolt passes the installation through-hole and sets up first recess with differential lock cylinder and vehicle fixed connection, corresponds installation through-hole department at the cylinder block terminal surface, and connecting bolt's top is placed in first recess, can reduce connecting bolt's length demand, increases joint strength, improves the aesthetic property simultaneously.
The utility model discloses further setting is: one side of the mounting boss is provided with a notch.
The utility model has the characteristics as above: the notch that installation boss one side set up makes things convenient for magnetic induction displacement sensor's installation, dismantlement.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
