Description

Snowmobile with resistance plate

Technical Field

The present disclosure relates to a snowmobile with a drag plate.

Background

Snowmobiles, also known as rudderbobsleits, have originated in switzerland and evolved from rudderbobsleits. The snowmobile is made of metal, and the head of the snowmobile is covered with a streamline cover, so the snowmobile is also named as a snowfield boat. The snowmobile starting stage is promoted by athletes, the promotion achievement is 1% in the boosting process, the gliding section can be promoted by 3%, and then the training in the boosting stage becomes particularly important.

Disclosure of Invention

At least one embodiment of the present disclosure provides a snowmobile with a drag-plate. The resistance board sets up at snowmobile locomotive air pressure concentration part to melt in an organic whole with the automobile body, in the boosting stage of training process, the resistance board can rise, changes the air current rounding off, makes the air current separate in advance, increases the resistance of snowmobile motion, and then improves the load of sportsman's training, promotes the motion ability.

At least one embodiment of the present disclosure provides a snowmobile, including a housing, the housing has a rotatable handle for pushing the snowmobile and a handle receiving portion for receiving the handle, the housing front end is provided with a resistance plate and a resistance plate receiving portion for receiving the resistance plate, the resistance plate is coupled with the handle through a transmission mechanism disposed in the housing, the resistance plate is driven to lift through the transmission mechanism during the rotation of the handle, wherein the resistance plate rises when the handle is unfolded, and the resistance plate is received in the resistance plate receiving portion when the handle is received in the handle receiving portion.

In some examples, the resistance plate edge is flush with the housing surface when the resistance plate is received in the resistance plate receiving portion.

In some examples, the transmission mechanism includes:

a first bevel gear connected with the handle;

a second bevel gear in mesh with the first bevel gear;

a third bevel gear disposed on a shaft with the second bevel gear;

a fourth bevel gear in mesh with the third bevel gear;

the cylindrical gear and the fourth conical gear are arranged on the other shaft; and

the rack is meshed with the cylindrical gear, and the resistance plate is fixed on the rack.

Detailed Description

The prior art snowmobile comprises a handle 2, a shell (body) 3, a fairing 4 and a sled 5. The handle 2 is rotatably disposed in a handle receiving portion (not shown) of the housing 3. In the boosting process, the handle is lifted, and the snowmobile is pushed to slide through the handle. When the sliding stage is close, the athlete enters the vehicle and takes the handle 2 into the handle containing part. When the handle 2 is accommodated in the handle accommodating part, the handle 2 and the shell 3 are integrated, namely the handle 2 and the shell 3 are flush, and a concave part or a convex part which influences the performance of the snowmobile cannot be formed on the vehicle body.

As shown in fig. 1 to 4, the present disclosure provides a resistance plate 1 and a resistance plate accommodating portion (not shown) at an air pressure concentration portion of a snowmobile head. The resistance plate is connected with the handle 2 through a transmission mechanism arranged in the shell 3, and the handle 2 drives the resistance plate 1 to lift through the transmission mechanism in the rotating process. When the handle 2 is lifted in the boosting stage, the resistance plate 1 can be lifted, the air flow is changed to be in smooth transition, the air flow is separated in advance, the air resistance of the snowmobile is increased, the training load of athletes is further improved, and the movement capacity is improved; when the sliding stage is close, the handle 2 is stored in the handle containing part, a sportsman enters the car, and the resistance plate 1 is also stored in the resistance plate containing part along with the sportsman. When resistance board 1 was accomodate into in the resistance board holding portion, resistance board 1 border and 3 surperficial parallel and level of shell, resistance board 1 and shell 3 fuse as an organic whole promptly, can not form the concave part or the arch that influence snowmobile performance on the automobile body.

As shown in fig. 5, the transmission mechanism includes: a first bevel gear 6 and a second bevel gear 7 which are meshed with each other; a third bevel gear 9 and a fourth bevel gear 11 which are meshed with each other; and a cylindrical gear 13 and a rack 14 which are meshed with each other. Wherein the handle 2 is connected with a first bevel gear 6, a second bevel gear 7 and a third bevel gear 9 are arranged on a shaft 8, a fourth bevel gear 11 and a cylindrical gear 13 are arranged on the other shaft 9, and the resistance plate 1 is fixed on a rack 14. The transmission mechanism is arranged on a rack 10 in the snowmobile, and bearings of the supporting shafts 8 and 9 are fixed on the rack 10. The handle 2 drives the first bevel gear 6 to rotate when rotating, simultaneously rotates with the second bevel gear 7 that first bevel gear 6 meshed, the third bevel gear 9 coaxial with second bevel gear 7 rotates, the fourth bevel gear 11 meshed with third bevel gear 9 rotates, the cylindrical gear 13 coaxial with fourth bevel gear 11 rotates, the cylindrical gear 13 drives the rack 14 and the resistance plate 1 fixed on the rack 14 to ascend and descend when rotating, wherein the resistance plate 1 can ascend when the handle 2 is lifted, and the handle 2 is accommodated into the handle accommodating part in-process resistance plate 1 can descend.

Claims (3)
