Description
Technical field
The present invention relates to a kind of axle-distance adjustable automobiles, belong to automobile technical field, is can be specially adapted to various four-wheel electric automobile by the automobile of chaufeur active adjustment apart from high between a kind of front and back wheel.
Background technology
Present automotive research all is being devoted to car acceleration, is steadily being reached the raising of aspect performance such as cross-country.Yet existing wheelbase fixed type automobile can not get bringing into play fully owing to the restriction that is subjected to ground attaching coefficient makes the power of driving engine when starting-up to speed, thereby has influenced the acceleration capability of starting low-speed stage.In addition, wheelbase fixed type automobile is if improvement becomes axle-distance adjustable automobiles, and then its off-road capability, grade climbing performance and stationary performance etc. also can be improved.In the prior art, a kind of adjustable technical scheme of wheelbase of diesel locomotive is arranged, still, spring on its back axle bears whole levels and vertical load simultaneously, force path is unreasonable, and its screw mandrel that is used for the adjusting shaft distance bears horizontal actuator force constantly, and reliability is not high.
Summary of the invention
The objective of the invention is to, overcome the shortcoming of prior art, the axle-distance adjustable automobiles that a kind of bearing load and force path are reasonable, drive reliably, can improve starting acceleration performance, grade climbing performance, off-road capability, balance and the deceleration and stopping performance of automobile is provided.
Technical scheme of the present invention is: described axle-distance adjustable automobiles, and it includes vehicle body, power system, running gear, control system; Described running gear has a wheelbase regulating mechanism that is used to regulate the distance between trailing wheel and the front-wheel; Described wheelbase regulating mechanism is mainly regulated screw mandrel, slip nut, wheelbase adjusting electrical motor and slippage beam by preceding dowel bar, back dowel bar, wheelbase and is formed; Preceding dowel bar one end connects to ground, and the other end flexibly connects with the slip nut that is sleeved on the wheelbase adjusting screw mandrel; The inboard load bearing of back dowel bar one end and trailing wheel flexibly connects, and the other end flexibly connects with the slip nut that is sleeved on the wheelbase adjusting screw mandrel; Wheelbase regulate electrical motor and wheelbase adjusting screw mandrel by meshed transmission gear, be connected; Wheelbase regulates the screw mandrel two ends and vehicle frame flexibly connects; The front end of slippage beam and vehicle frame flexibly connect, and its top connects to ground by damping spring, and there is a carrying groove its underpart; Supporting rollern is enclosed within on the rear axle, and embeds in the carrying groove.
Technique effect of the present invention is:
1, can change its maximum acceleration from rest by regulating the distribution of axle load on front and back wheel, and the adjusting of the change that axle load distributes by wheelbase realizes.
2, improve the steerability of automobile.Automobile will move behind the rear axle when running at high speed, and the axle load that can increase front axle is transferred, thereby improves the steerability energy of automobile.
3, meet muddy pitting and trailing wheel when skidding at automobile, just can cross the mud pit for the method that general-utility car has only usefulness to fill out hole or firmly go-cart, and, then can pass through a motion trailing wheel for the adjustable automobile of rear axle, make vehicle body keep motionless, thus make trailing wheel " time " cross the mud pit.
4, reduce the vibration intensity of automobile.On the three-dimensional coordinate surface chart by the speed of a motor vehicle, wheelbase and three factors draftings of vibration intensity a trough band that the body vibrations intensity ratio is less is arranged, thereby can reach the stability of taking preferably by the relation between the adjusting shaft distance and the speed of a motor vehicle.
5, the spring bearing load on the slippage beam is reasonable, and the car load force path is reasonable, and its screw mandrel that is used for the adjusting shaft distance to bear propulsive effort reasonable, the reliability height.
