Abstract

The utility model is related to racing car model technical field, more particularly to a kind of two-wheel car mould.The utility model includes chassis, the rear end upper surface on chassis is provided with support block, support block is connected with two trailing wheels and drives two drive mechanisms of rear wheel movement, the lower surface on chassis is provided with the reinforcement of a plurality of projection, reinforcement is integrally formed with chassis, the length on chassis is L, and the centre distance of two trailing wheels is M, 0.9M<=L<=1.2M.The utility model is by the way that the support block of fixed wheel assembly to be arranged on the upper surface on chassis, and reinforcement is arranged on lower surface, so that the center of gravity on chassis is effectively reduced, secondly, define the length on chassis so that chassis can keep relatively low gradient in the process of running.

Description

A kind of two-wheel car mould

Technical field

The utility model is related to racing car model technical field, more particularly to a kind of two-wheel car mould.

Background technology

Model car races generally receive an acclaim in teenager, there is kind of a two-wheel car mould ratio during model car races Match, car mould is inclined upwardly against two trailing wheel operations, chassis front end；In the process of running, speed is by earth for this two-wheel car mould The influence of disk gradient, if gradient is larger, car mould is more steady, but speed is slower, if gradient is smaller, car mould Smoothness is affected, speed.Presently, this two-wheel car mould due to chassis design is not quite reasonable, it is necessary to tie up Chassis is held in larger gradient, so as to have influence on game tempo.

The content of the invention

The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of two-wheel car mould, the two-wheel car mould Chassis size is optimized, and relatively low gradient can be kept during the games, and car mould stability is preferable.

The technical solution adopted in the utility model is：

A kind of two-wheel car mould, including chassis, the rear end upper surface on chassis are provided with support block, and support block is connected with two trailing wheels And two drive mechanisms of rear wheel movement are driven, the lower surface on chassis is provided with the reinforcement of a plurality of projection, reinforcement and chassis It is integrally formed, the length on chassis is L, and the centre distance of two trailing wheels is M, 0.9M<=L<=1.2M.

Further, the support block is connected with two drive mechanisms, and each drive mechanism is corresponding with trailing wheel to be driven Connection.

Preferably, transmission mechanism is provided between drive mechanism and trailing wheel.

Further, drive mechanism includes motor, and transmission mechanism includes the driving gear being socketed with the rotating shaft of motor, And the driven gear being socketed with the rotary shaft of trailing wheel, driving gear engages with driven gear.

Yet further, support block is connected with the encoder being engaged with drive mechanism, and encoder is connected with counting gear, Counting gear is engaged with driven gear.

The beneficial effects of the utility model are：The utility model is arranged on chassis by by the support block of fixed wheel assembly Upper surface, and reinforcement is arranged on lower surface, so as to effectively reduce the center of gravity on chassis, secondly, defines the length on chassis, So that chassis can keep relatively low gradient in the process of running.

Specific embodiment

Embodiment：Referring to Fig. 1, Fig. 2.

A kind of two-wheel car mould, including chassis 1, the rear end upper surface on chassis 1 are provided with support block 8, and support block 8 is connected with two Two drive mechanisms of the motion of trailing wheels 2 of trailing wheel 2 and driving, the lower surface on chassis 1 is provided with the reinforcement 11 of a plurality of projection, strengthens Muscle 11 is integrally formed with chassis 1, and the length on chassis 1 is L, and the centre distance of two trailing wheels 2 is M, 0.9M<=L<=1.2M.

In the technical program, using the structure on the chassis 1 of integration, while the axle of trailing wheel 2 to be arranged at the upper surface on chassis 1 Support block 8 on so that the decentralization of chassis 1；Secondly, the reinforcement 11 that chassis 1 is set also is located at the lower surface on chassis 1, more Further auxiliary lowers the center of gravity；In order that obtain chassis 1 is at less gradient in car mould motion process, here will The length on chassis 1 is limited so that the characteristics of upper surface on chassis 1 has short flat, operation stability is preferable.

Further, the support block 8 is connected with two drive mechanisms, and each drive mechanism is corresponding with trailing wheel 2 to drive Dynamic connection.

Two drive mechanisms are set and drive two trailing wheels 2 respectively so that the rotating speed of trailing wheel 2 can be controlled individually, because This can be very good control turning velocity difference and turning velocity when turning to so that car mould remains to be kept for one when turning The speed of service higher.

Preferably, it is provided with transmission mechanism between drive mechanism and trailing wheel 2.

Transmission mechanism is set, speed governing can be carried out and distance regulation is convenient to.

Further, drive mechanism includes motor 7, and transmission mechanism includes the driving gear being socketed with the rotating shaft of motor 3, and the driven gear 5 being socketed with the rotary shaft of trailing wheel 2, driving gear 3 is engaged with driven gear 5.

Transmission mechanism is gear assembly, can adjust the output speed of motor.Certainly idler gear can also be set here, Driving gear 3 is connected by idler gear with driven gear 5, the design of idler gear, can be used for adjusting the position of motor.When So, transmission mechanism can also be synchronous wheel drive mechanism, and active synchronization wheel is socketed on machine shaft, be socketed in rotary shaft driven same Step wheel, active synchronization wheel is connected by Timing Belt with driven synchronizing wheel.Certainly can also be chain-wheel mechanism, by chain drive.

Yet further, support block 8 is connected with the encoder 6 being engaged with drive mechanism, and encoder 6 is connected with counting tooth Wheel 4, counting gear 4 is engaged with driven gear 5.

Design encoder 6, can obtain the actual speed of trailing wheel 2, the convenient speed with control trailing wheel 2.

The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in, Should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims Enclose and be defined.
