Abstract
A vehicular variable-speed system is provided with a transmission for connecting a flywheel shaft with a driving axle of a vehicle. The transmission is provided with a drive belt and two belt pulleys, contact faces of the two belt pulleys are provided with mutually-meshed grooves so as to facilitate drive, one of the two belt pulleys is in the shape of a right cylinder while the other of the two belt pulleys is conical frustum shaped, and meshing grooves on the conical frustum shaped belt pulley are gradually increased from a small diameter end to a large diameter end, so that meshing grooves on the drive belt are well meshed with the meshing grooves on the conical frustum shaped belt pulley. One side of the conical frustum shaped belt pulley is abutted against by a fluid pressure cylinder in a sliding fit manner, and a cylinder body is communicated with a fluid pressure pump. The fluid pressure pump is controlled to be operated or halt by a gear-shift operating component, so that the fluid pressure cylinder is pushed to move axially to press the conical frustum shaped belt pulley at proper gears.
Description
Technical field
The present invention relates to a kind of vehicle speed variation system, be particularly a kind ofly easy to the vehicle speed variation system of even braking of slowing down.
Background technique
Vehicle of the prior art is all brake by means of brake pad, consumes many energy in braking process.These energy can not reclaim, and cause waste.
Vehicle of the prior art, from all will to touch on the brake during high gear gear down position or idling travels for a long time, can be shifted gears after speed being reduced, and can not direct kickdown immediately at high speeds, realizes slowing down.This dissipates equally and wastes a large amount of kinetic energy.
Summary of the invention
The present invention is intended to reduce the energy ezpenditure in car brakeing and moderating process, reaches the effect of energy-saving and emission-reduction.
To achieve these goals, the vehicle speed variation system of a kind of inventor creation is released at this, it has the speed changer flywheel shaft of vehicle and axle shaft coupled together, and this speed changer has driving belt and two belt wheels, on the surface of contact of the two with engaging each other so that the groove of transmission; One of two belt wheels are straight circular cylinder type, another is round table-like, the end face of round platform and bottom surface have the disk that diameter is obviously greater than the diameter of a circle at round platform corresponding surface place respectively, this belt wheel is departed to prevent driving belt, and the described engaging groove on this round table-like belt wheel increases gradually from smaller diameter end to larger diameter end, make the engaging groove good engagement on the engaging groove on driving belt and round table-like belt wheel; The major diameter side of round table-like belt wheel is withstood by fluid pressure cylinder with being slidably matched, and cylinder body leads to the Decompression valves of a low-pressure cavity with the high pressure valve and one that lead to a hyperbaric chamber; Described hyperbaric chamber keeps the high pressure of a setting by fluid pressure pump, this high pressure make when high pressure valve open and by described fluid pressure cylinder and described hyperbaric chamber UNICOM time, the plunger of this fluid pressure cylinder can promote described round table-like belt wheel and move axially, and round table-like belt wheel is pressed in suitable gear; Described fluid pressure pump is controlled by a controller, also starts according to the force value preset and stops, hyperbaric chamber is kept the high pressure of described setting by means of pressure transducer; Immediately below driving belt, be fixed wtih one for the stop member of backstop driving belt, when moving axially to avoid round table-like band crop rotation, driving belt together moves; The lower end of this stop member can vertically be arranged in a vertical slots movably, and is connected with the maximum diameter end of round table-like belt wheel by a connecting rod.The two ends of this connecting rod respectively with the maximum diameter end of round table-like belt wheel and the lower end of described stop member pivotally connected, its length is substantially equal to the length of round table-like belt wheel.
Preferably, the belt wheel be fixedly connected with axle shaft is round table-like belt wheel.
Preferably, the distribution of the pulley diameters of round table-like belt wheel makes flywheel shaft pulley diameters be less than 1/500 with the minimum ratio of axle shaft pulley diameters, makes almost to play braking action when vehicle idling travels or be flame-out when two belt wheels are in the position of minimum diameter ratio.
Preferably, described high pressure valve is configured to be opened by the withdrawal of gas pedal, stepping on of gas pedal and closing, and described Decompression valves is arranged through stepping on of gas pedal and opens, and is closed by the withdrawal of gas pedal.Like this, driver can operate the vehicle that speed variator system of the present invention is housed with familiarity driver behavior.
Preferably, described gas pedal is also arranged to control spark plug and fuel nozzle simultaneously, and make the spark plug when regaining gas pedal stop igniting, fuel nozzle also stops oil spout, and when step on the throttle pedal time spark plug start igniting, fuel nozzle also restarts oil spout.Fuel consume can be greatly reduced like this.
Preferably, described fluid pressure cylinder coordinates with the described opposite side end face of described round table-like belt wheel is dynamic by means of a disk ball bearing.
Preferably, described fluid pressure cylinder is a cylinder shape oil hydraulic cylinder coaxial with described round table-like belt wheel.
Preferably, described fluid pressure pump is oil hydraulic pump.
Preferably, the length of the connecting rod coupled together by the maximum diameter end of the lower end of described stop member and round table-like belt wheel is selected make described stop member always very near the edge of round table-like belt wheel, but not with this EDGE CONTACT.
Those skilled in the art read this and are not difficult to find out, by vehicle speed variation system of the present invention, vehicle can realize direct kickdown and slow down, and the gear shift again of slowing down that need not first touch on the brake, and, by speed variator system, the kinetic energy part before vehicle deceleration is transferred to flywheel to be in store, instead of dissipates as prior art.Therefore, present invention achieves energy-saving and emission-reduction, environmental friendliness.
It is noted, however, that vehicle can not replace braking device completely with above-mentioned speed variator system.Because if even brake with such transmission reduction when descending, then flywheel speed can be made more and more faster, cause danger.Therefore, also need to be furnished with frictin braek to use in order to during descending.Advise a kind of barb-type break, it has a keep plate.This keep plate is contained on the bottom surface of vehicle by an elevator mechanism, and the one side of itself and earth surface is with the reverse hangnail in vehicle forward direction.This keep plate is preferably arranged on the near rear wheels of vehicle or than trailing wheel more rearward position, its elevator mechanism is preferably arranged to when keep plate is braked, and it applies power and backward downwards to vehicle.According to the deadweight tonnage of vehicle, one or more such barb-type break can be set.
As supplementing or substituting barb-type break, keep plate can have a chamber, it is built with a kind of high viscosity semiliquid, with on the face of earth surface with some wheels leading to chamber interior, when these take turns roll on the ground time, viscous semi-liquid in chamber is taken out of, thus and produce cohesive force between ground, stop vehicle acceleration.
