Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] figure 1 , 2 Shown is the overall structure diagram, and the connection relationship of each part must be correct and the installation should be firm.

[0022] The brake is composed of four brake springs, four static friction plates, and three dynamic friction plates to complete wet braking under the action of brake oil in and out.

[0023] Cooling is carried out by the cooling oil inlet and outlet valves, oil inlet and outlet pipes, and piston cavity for external circulation of cooling oil.

[0024] All oil pipes, oil passages and oil chambers must be clean and unimpeded.

[0025] image 3 , 4 , 5, 6, and 7 show the positions of cooling oil inlet and outlet valves, brake oil inlet and outlet ports, lubricating oil inlet and outlet ports, vent plugs, screw plugs, screws and spline sleeves, and spline shafts. The positions of each part are arranged reasonably.

Abstract

The invention relates to a brake with cooling in a driving axle of a battery forklift, which mainly comprises a piston shell body, a piston body, a piston cavity, a cooling inlet and outlet oil valve,a left axle body and a right axle body, a transmission shaft, a spline shaft, a spline sleeve, a braking spring, a dynamic friction plate and a static friction plate, a braking inlet and outlet oil port, a lubricating inlet and outlet oil port and screws. A wet-type brake in the driving axle is provided with double circuits for braking and cooling and a double-cycle and synchronous structure anduses the same hydraulic oil tank, the cooling inlet and outlet oil valve is started synchronously while braking to carry out cooling external circulation, and the braking spring ensures clearance to generate between the dynamic friction plate and the static friction plate, thus eliminating the friction force, avoiding heating bonding and solving the problem of synchronous braking and cooling well.The device has advanced and reasonable design, compact structure, safe, steady and reliable properties and convenient installation and use and is an ideal brake with cooling for the battery forklift,and the device can also be used in other similar vehicle types.

Description

technical field [0001] The invention relates to a drive axle internal brake with cooling for a storage battery forklift, which belongs to the technical field of design and manufacture of auxiliary transportation equipment parts in coal mines. Background technique [0002] The battery forklift is an important auxiliary transportation equipment in coal mines. Its traveling mechanism is a drive axle slewing structure. A wet brake is installed between the drive axle and the wheel hub. When the vehicle goes down a long-distance slope, it needs continuous braking to overcome the force of gravity At this time, the long-term friction between the friction plates of the brake will generate a lot of heat, which will easily cause the friction plates to stick together, resulting in brake failure, damage to the brake, potential safety hazards to the vehicle, and even danger. Sometimes it is necessary to Artificially cooling, the effect is not good, and it is also very inconvenient. Cont...
