Abstract

FIELD: transport.

SUBSTANCE: running gear comprises wheel, rocker bar, road rollers fitted on rocker bar free ends and controlled retainer of rocker bar position relative to the wheel. Said rocker bar is composed of two shafts spinning timed with the wheel and equally spaced apart in the wheel lengthwise plane. Said road rollers are composed by cylindrical gummed spring and/or that coated with resilient material to connected rocker bar shafts in the wheel crosswise plane. Rocker bar shafts can be parallel or perpendicular to the wheel lengthwise plane.

EFFECT: decreased resistance of propulsor.

Description

The invention relates to transport engineering, in particular to uniaxial propulsion vehicles, including wheelchairs.

The known chassis of the vehicle / see author testimonial. No. 1 556992 (CL B62D 55/04) dated 06/23/1988 /, containing a wheel, a balancer, track rollers mounted on the free ends of the balancer, a controlled position lock of the balancers relative to the wheel.

The known chassis prototype is unreasonably complicated if its design and technology are applied to the manufacture of uniaxial propulsion vehicles.

To simplify, reduce the cost and unify the manufacturing technology of uniaxial propellers in the chassis of a vehicle containing a wheel, a balancer, track rollers mounted on the free ends of the balancer, a controlled lock position of the balancers relative to the wheel, the balancer is made in the form of two shafts rotating simultaneously with the wheel and equally spaced from the longitudinal plane of the wheel, and the function of the support rollers is performed by a cylindrical gummed and / or coated with elastic material spring connecting the balancing shafts in the transverse plane of the wheel. In this case, the balancing shafts can be parallel or perpendicular to the longitudinal plane of the wheel.

The vehicle chassis proposed by the technical solution is illustrated by a simplified figure in the position when the balancing shafts are parallel to the longitudinal plane of the wheel, front view.

The undercarriage of the vehicle comprises a wheel 1, a balancer in the form of two shafts (2 and 3), a support roller in the form of a cylindrical gummed and / or coated with elastic material spring 4 connecting the balancing shafts (2 and 3) in the transverse plane of the wheel 1. Controlled latch the position of the balancers (2 and 3) relative to the wheel 1 in FIG. not shown.

The chassis of the vehicle proposed by the technical solution simplifies, reduces the cost and unifies the technology of manufacturing uniaxial propulsion vehicles / see, for example, US Pat. No. 2298304 (class A01B 49/00) dated 04/04/2005 /, replacing the track rollers of the prototype front and rear of the main drive wheel, necessary primarily at the stage of acceleration and braking, with a coil spring rotated by means of a balancing shaft (as in FIG.) or balancing shafts simultaneously with the wheel. The use of a spring instead of twin rollers (as in the prototype) also minimizes the resistance, especially noticeable when turning and turning the vehicle.

Thus, according to the applicant, the proposed technical solution is new, has an inventive step and is industrially applicable.

Claims (2)
