Abstract

The utility model relates to a novel manpower car which belongs to a transportation vehicle. The manpower car is improved on the basis of the manpower car of zl 022511490 of the prior art, and a chain transmission mode of the prior art is changed into a hydraulic transmission mode, specifically as following: a plunger oil pump or a gear oil pump, a three-position four-way valve and an oil tank are fixed on a main bridge of a chassis; high-pressure oil pipes are arranged among the plunger oil pump or the gear oil pump, the three-position four-way valve and a hydraulic motor which his fixed on an ear plate of a spring plate of a rear wheel; a one-way valve and the oil tank are arranged on one high-pressure oil pipe which is connected among the plunger oil pump or the gear oil pump and the three-position four-way valve; an automatic clutch is arranged on a half shaft of the rear wheel; a pedal plate is connected with a plunger rod or a pedal crankshaft of the plunger oil pump or the gear oil pump. With a speed which can be more than 40 kilometers per hour, the car has the advantages of environmental protection, saving of energy, body building, practicality, cheapness, little energy consumption and noiselessness, and is suitable for daily short-distance traffic and medium-distance and long-distance leisure tourism.

Description

Self-operated car

Technical field: the utility model relates to a kind of later-model Self-operated car in the vehicle.

Background technology: the bicycle of the existing vehicle can only a people be ridden, and does not becalm, sand, rain, snow, easily falls and hurts oneself during the cunning of road surface.Though the fuel oil car has overcome above-mentioned deficiency, because cost is too high, expense is big, contaminated environment.From the social development angle, bicycle and fuel oil car must be eliminated.And the development of solar car and universal also needs one quite long period, and in this sense, the inventor designed a kind of Self-operated car in 2002, and had applied for patent, and the patent No. is ZL022511490.This car utilizes the most strong muscle of human body---four vastus, the power of pedaling of design level, the power that produces the human body maximum is done the power of Self-operated car, the time 20 kilometers/hour of scooters.But we also find in the practice, because the power pack section of this car adopts chain transmission mode, so it is big to exist waste of power under steam, and chain shortcoming such as easily come off during the big high-speed operation of noise, and influenced moving velocity.

Summary of the invention: in order to overcome the deficiency that patent No. ZL022511490 Self-operated car exists, Self-operated car of the present utility model improves on the basis of prior art ZL022511490 Self-operated car, change the chain transmission mode in the prior art into hydrostatic drive, the concrete practice is: non-movable piston oil pump or geared oil pump on the bridge of chassis, three-position four-way valve and fuel tank, at plunger fuel pump or geared oil pump, three-position four-way valve be fixed on trailing wheel spring plate otic placode on HM Hydraulic Motor between be connected high pressure fuel pipe, on the pipeline of a high pressure fuel pipe of bonded assembly between plunger fuel pump or geared oil pump and three-position four-way valve, be provided with check valve, fuel tank, on the trailing wheel semiaxis, self-acting clutch is housed, stretcher is connected with the plunger rod or the foot-operated crank rod of plunger fuel pump or geared oil pump, utilize rotatablely moving of stretcher crank motion or foot-operated crank rod, drive plunger fuel pump or geared oil pump, under doing of check valve used, produce directed high pressure oil stream, flow to the HM Hydraulic Motor that is located at the car rear portion by three-position four-way valve, make it to drive back wheels of vehicle and rotate, the driving Self-operated car advances or retreats.This car is except having the environmental protection identical with prior art, energy-conservation, body-building, practicality, cheap characteristics, most importantly its energy consumption is little, noiselessness, and speed per hour is the twice of prior art, can reach more than 40 kilometers/hour, be applicable to daily short distance traffic and in way far away go on tour used.

Description of drawings: accompanying drawing 1 is the structural representation of the utility model Self-operated car.Accompanying drawing 2 is the upward view of accompanying drawing 1.Accompanying drawing 3 is the structural representation of the propons in the accompanying drawing 2 19.Accompanying drawing 4 is the fundamental diagram of embodiment 2 medium powers part.

The specific embodiment: for the structure to the utility model Self-operated car has further understanding, details are as follows in conjunction with embodiment of the present utility model:

Embodiment 1, Self-operated car

With reference to accompanying

drawing

1,2,3, the structure of Self-operated car of the present utility model comprised among the figure with the existing fuel oil car essentially identical car body part that constitutes by car door 1, car shell 2, vehicle window 3, chassis bridge 9, wheel 10, vehicle seat 14; By four plunger fuel pumps 6 that are fixed on the chassis bridge 9, three-position four-way valve 11, fuel tank 12, be fixed on the HM Hydraulic Motor 13 on the trailing wheel spring plate otic placode, connect 4 plunger fuel pumps 6, three-position four-way valve 11, fuel tank 12, the high pressure fuel pipe 8 of HM Hydraulic Motor 13, on the pipeline of a plunger fuel pump 6 and a high pressure fuel pipe 8 of three-position four-way valve 11 bonded assemblys, connect four unit valves 7 successively from plunger fuel pump 6 one ends, fuel tank 12, fixingly on chassis bridge 9 pass through the pedal brake 23 that connecting rod acts on trailing wheel 10 wheel rims, with the self-acting clutch 24 that is equipped with on the trailing wheel semiaxis, and an end fulcrum is fixed on the power pack section that plunger rod bonded assembly stretcher 5 on the chassis bridge 9 and plunger fuel pump 6 constitutes; Also comprise by propons 19 fixing on the chassis bridge 9, by the two clamping plates 15 of bolted connection below propons 19 two ends, the stub axle 16 that in the stomidium of propons 19 and clamping plate 15, is provided with, the damping spring 20 that is with on the longitudinal axis of stub axle 16, pressure bearing 21, the Linkage steering 18 that vertical termination of stub axle 16 is connecting, the bearing circle 4 that direction of passage dish connecting rod 17 is connecting, the knuckle section that the bearing carrier ring of fixing on the stub axle 16 horizontal axle heads 22 constitutes.Wherein the three-position four-way valve in the power pack section 11 is connecting four high pressure fuel pipes 8, and two of front end are communicated with plunger fuel pump 6, and two of rear end are communicated with HM Hydraulic Motor 13.
