Abstract
A telescopic-wheeled car comprises car wheels, a car frame, a power transmission shaft, a steering control lever, an axle and a lift control device. The lift control device comprises a three-stage drive telescopic cylinder and a hydraulic oil pump. The lift control device is driven by a hydraulic drive multistage telescopic cylinder, and the oil pump injects oil into the cylinder to transmit power to the cylinder. The telescopic-wheeled car has the advantages that the car body can be adjusted higher by about 1 meter in the process of car running, and the car body can be completely separated from the water surface in case of general water accumulation, thereby guaranteeing engines and circuit devices to avoid soaking in water, ensuring the safety of vehicles and persons, and reducing the driving resistance.
Description
Technical field
The utility model relates to a kind of adjustable for height roadlice, specifically is to use hydraulic gear to regulate the roadlice of height between car body and the wheel.
Technical background
Because urban operating mechanism is aging, can not get keeping in repair timely, especially in the old town in some cities, underfloor duct mediation situation and condition of road surface are all very poor, often cause surface gathered water, and the automobile that at this moment rests in the roadside will be suffered disaster.When ponding deepens, when automobile can not in time leave, will by bubble in water, bring loss for the owner of automobile, also can only detour through the roadlice here equally and go, make troubles to the people of steering vehicle; Holiday, whole family's tourism of going on a journey ran into the muddy water hollow, and general-utility car can't pass through again, can have influence on the mood of going on a tour unavoidably; Summer and autumn, heavy rain increases, and runs into that some automobiles can be hided nowhere and is flooded the top through regular meeting, and automobile should be that people are convenient, the instrument of leisure, now, but usually because the low excessively problem of car chassis, and brings worry to the people.
Summary of the invention
For addressing the above problem, the utility model provides a kind of scalable wheel roadlice, can change the height of automobile at any time, and just the relative height between wheel and the car body can be regulated.Height between wheel and car body hour, just the same with other general roadlice, can on usual road surface, travel, but when both height adjustment during, just can wade, and the resistance that automobile is subjected to when wading is much smaller to certain altitude, this function also is applicable to cross-country vehicle, relative amphibious vehicle and air-ground amphibious car, manufacturing technology is simple relatively, and cost is also much lower.
The technical solution of the utility model is: a kind of scalable wheel roadlice, comprise wheel, vehicle frame, power drive shaft, direction control stalk, vehicle bridge and elevation and subsidence regulating device, described elevation and subsidence regulating device comprises three grades of transmission telescopic oil cylinders and hydraulic oil pump, described elevation and subsidence regulating device is by this hydrostatic drive multi-stage expansion oil cylinder transmission, the oiling and transmit power to oil cylinder in oil cylinder of described oil pump.
Described elevation and subsidence regulating device comprises before two platforms three grades of telescopic oil cylinders of hydrostatic drive and corresponding bumper and antivibration spring behind three grades of telescopic oil cylinders of hydrostatic drive and two platforms; Wherein, described before the upper end of three grades of telescopic oil cylinders of hydrostatic drive be fixed on the vehicle frame front mounting plate, before the lower end is fixed on the vehicle bridge, the upper end of three grades of telescopic oil cylinders of described back hydrostatic drive is fixed on behind the vehicle frame on the adapter plate, the lower end is fixed on the vehicle bridge of back.
Described power drive shaft is a spline shaft structure, this castellated shaft comprises hub splines and spline axostylus axostyle, and axle sleeve and axostylus axostyle drive except driving engine and the rotation, also can make axial motion between axle sleeve and the axostylus axostyle, satisfy by height of the carbody with this and to change, and make variable in distance between driving engine and the back axle.
Three grades of oil cylinders of described hydrostatic drive comprise base, O-ring seal, packing ring, nut and stretch out the action oil inlet.
The front-wheel of described scalable wheel roadlice and the direction control stalk between the bearing circle are spline shaft structure.
The concrete structure of bumper of the present utility model and damping spring and present disclosed technology are as broad as long, do not give unnecessary details at this.
Principle of work of the present utility model is: when needs are regulated height of the carbody, start the oiling in oil cylinder of hydraulic transmission oil pump, the car body that the oil cylinder elongation promotes on it raises, and makes the height that car body is elevated to be needed.And car body be need descend the time, and oil pump is extracted in-oil cylinder hydraulic oil out, car body by gravity automatic lowering.
The utility model has the advantages that: car body can be heightened about one meter in the vehicle ' process, if run into general ponding, the car body and the water surface are left fully, guarantee that driving engine and circuit devcie are not immersed in water, guarantee vehicle and people's safety, and reduced garage's resistance.Motionless when vehicle stationary, can't leave running into the accident vehicle, and when guaranteeing automotive safety again, car body can be adjusted to about two meters, can guarantee vehicle safety to greatest extent.
