Abstract
The utility model discloses a single-cylinder motor vehicle odometer, consisting of an odometer (11), an odometer line (12), a distance and speed testing mechanism (13). A worm (15) of the distance and speed testing mechanism (13) is fixedly connected with a shaft head of a transmission shaft (7) extended out of a gearbox (1) by a key (20); the worm (16) is arranged in a worm sleeve (21) and is connected with the odometer (11) by the odometer line (12). The distance and speed testing mechanism (13) can be arranged any one transmission shaft (7) of the gearbox. Matched with the single-cylinder motor vehicle connecting-body rear axle, the utility model can transmit the rotation of the drive roller on the odometer (11) for display by the rotation of the transmission shaft (7) of the gearbox through the distance and speed testing mechanism (13) and the odometer line (12), providing extremely large convenience for the driver to drive the vehicles and to master the vehicle speed and vehicle conditions.
Description
(1) technical field
The utility model relates to the automobile-use mileometer, relates to the motor vehicle mileometer technical field that is used as power with single cylinder engine specifically.
(2) background technology
The conjuncted back axle of the many employings of single cylinder engine motor-car speed change at present, by gearbox body (1), axle tube assembly (2), gear wheel (3), bearing (4), speed gear (5), belt pulley (6), transmission shaft (7), declutch shift shaft (8), shift fork seat (9), shaft-cup parts such as (10) are formed, belt pulley (6) connects with engine output shaft by vee belt, engine drives belt pulley (6) and rotates, carry out multistage transmission gear shift by serial speed gear (5) and transmission shaft (7) in the gearbox body (1) according to certain gear ratio, power transmission to gear wheel (3), is driven trailing wheel by axle tube assembly (2) and rotates.Its each gear speed is generally calculated when product design in advance.The instantaneous velocity of this structure when the motor vehicle cruising can not intuitively show, can not write down distance travelled, and convenient inadequately during use, the driver can't in time grasp speed of a motor vehicle vehicle condition, lacks effective foundation when going wrong place under repair or three guarantees for products service.
(3) summary of the invention
The purpose of this utility model just provides the automobile-use mileometer new structure that a kind of single cylinder engine is used as power, and can match with the conjuncted back axle of single cylinder engine motor-car.The operating range and the instantaneous velocity that can reflect motor vehicle reality accurately are convenient to the driver and are grasped speed of a motor vehicle vehicle condition.
Task of the present utility model is finished like this: design a kind of single cylinder engine motor-car mileometer, form by mileometer (11), mileometer line (12), span velocity measurement mechanisms (13), span velocity measurement mechanisms (13) comprises worm screw (15), worm gear (16), outer cover (17), worm gear set (21) etc., worm screw (15) is fixedly connected on the transmission shaft (7), form transmission with worm gear (16) engagement, outer cover (17) is enclosed in worm screw (15), worm gear (16) on the gearbox body (1).Worm screw (15) is fixedlyed connected with the transmission shaft that leans out gearbox body (1) (7) spindle nose with key (20), and fastening in addition with plain cushion (18) and back-up ring (19).Worm gear (16) is contained in the worm gear set (21), and by connecting the mileometer (11) on mileometer line (12) the connection pilot dial plate.Span velocity measurement mechanisms (13) can install on any transmission shaft (7) of wheel box.Mileometer (11), mileometer line parts such as (12) are identical with the prior art structure.
Design and produce, install, test according to above-mentioned, proof the utility model matches with the conjuncted back axle of single cylinder engine motor-car, the rotation of driving wheel can be transferred to mileometer (11) by the rotation throughput of jack shaft (7) apart from velocity measurement mechanisms (13) and mileometer line (12) goes up and shows, can reflect the motor-driven vehicle going distance and the speed of a motor vehicle accurately, the grasp speed of a motor vehicle and vehicle condition provide convenience during for driver's steering vehicle, especially the single cylinder engine agricultural vehicle are had bigger practical value.
