Connect filling pump；The pipe-line system is made up of oil inlet pipe, main oil pipe, oil distributing pipe and four-way allotter, oil inlet pipe connection makeup oil
Case and filling pump, main oil pipe connection four-way allotter, four-way allotter connects pushing tow cohesion device by oil distributing pipe；The oiling
Pump supplements fuel tank by oil inlet pipe connection.
Between a diameter of 100mm-500mm of the braked wheel.
The pushing tow cohesion device needs even number to use cooperatively in a group of motors, and pushing tow cohesion device is arranged on bag
Brake scotch, oil cylinder and support are included, the support is arranged on base, and the oil cylinder is provided with piston, and piston is provided with sealing ring,
Piston abuts brake scotch.
The foot-operated oiling pump box and filling pump connect, and foot-operated oiling pump box is provided with locking press button and brake pedal.
Present invention advantage compared with prior art is：The present invention has powerful braking function, can hommization step-less adjustment
Braking moment；During braking, operator can realize row according to the size of foot-operated dynamics, the overall process of smooth steady ground control braking
" on schedule " positioning of car, improves work efficiency, it is to avoid (the electric traditional method of indicating the pronunciation of a Chinese character) braking is caused to the damage inside mining electric locomotive.Brake force
Needs are used away from the powerful equipment safety that is sufficient for；The reliable compensation function of follow-up automatically can save the work in adjustment gap
Amount, it is ensured that brake is effective all the time；Without the need for driven by power, any instant all can be used effectively, and save energy.Overall structure is closed
Reason, installation, maintenance is convenient, and strong, movement response does not lag because of braking moment thoroughly to solve conventional brake, and the safety for existing
Hidden danger.
The present invention can be used on mining electric locomotive, the existing mechanical braking mode for using on effectively solving mining electric locomotive
Functional reliability is low, braking moment is too small, and operate reaction to lag to wait not enough, and operator, when using, driving positioning is deficient
It is good, in emergency circumstances force safety arrestment the defect such as cannot effectively realize.

Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of brake in the present invention.
Fig. 3 is the structural representation of pushing tow cohesion device in the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mining electric locomotive rides wheeled hydraulic brake system, including brake 1, system
Driving wheel 2, foot-operated oiling pump box 3, filling pump 4, supplementary fuel tank 5 and pipe-line system 6, the brake 1 includes base 1-1 and two
Pushing tow cohesion device 1-2, the braked wheel 2 is installed on motor 7 or reductor spindle nose, and braked wheel 2 is located at the both sides of brake 1
Two pushing tow cohesion devices brake scotch 1-3 between, the pushing tow cohesion device 1-2 by pipe-line system 6 connect filling pump
4, the pipe-line system 6 is made up of oil inlet pipe 6-1, main oil pipe 6-2, oil distributing pipe 6-3 and four-way allotter 6-4, and oil inlet pipe 6-1 connects
Supplementary fuel tank 5 and filling pump 4 are connect, main oil pipe 6-2 connection four-way allotter 6-4, four-way allotter 6-4 is connected by oil distributing pipe 6-3
Meet pushing tow cohesion device 1-2；The filling pump 4 supplements fuel tank 5 by oil inlet pipe 6-1 connections.
Between a diameter of 100mm-500mm of the braked wheel 2.
The pushing tow cohesion device 1-2 needs even number to use cooperatively in a group of motors, and pushing tow cohesion device 1-2 sets
Put including brake scotch 1-21, oil cylinder 1-22 and support 1-23, the support 1-23 is arranged on base 1-1, the oil cylinder 1-
22 are provided with piston 1-25, and piston 1-25 is provided with sealing ring 1-23, piston 1-25 connection brake scotch 1-21.
