Abstract
The utility model relates to a speed measuring device for a vehicle, particularly a speed measurer which uses friction as a speed measuring method. As the utility model uses a mechanical device in the speed measuring device, the cost is low, and the maintenance is easy. The speed measurement of a friction mode has the characteristics of sensitive response and accuracy; as the utility model uses a mechanical device, the installation is simple and convenient. Simultaneously, as an odometer is arranged, the user can conveniently calculate the traveling distance and can calculate the average speed.
Description
The utility model relates to a kind of speed counting device of vehicle, a kind of specifically velometer that utilizes friction as speed-measuring method.
Vehicle meter speed is the accessory that vehicle all need be installed, and comprises motorcycle and some high-grade bikes.Method commonly used at present has a lot, for example produce electromotive force by vehicle wheel spoke cutting magnetic field (magnetic line of force), perhaps calculate etc. by the break-make and the time of light, but these methods have the cost height, test the speed not accurate enough or the instability that tests the speed, easily produce shortcoming such as fault, always bring some inconvenience to the user.
The purpose of this utility model be a kind of cost of invention low, test the speed stable and not easy break-down, velometer easy to use.
The utility model can be achieved through the following technical solutions:
A kind of velometer, by speed measuring device, transmitting device and metering device are formed, speed measuring device is by geometrical clamp (11), shell (14) and velocity measurement mechanisms are formed, transmitting device is made up of transmission line and transfer connector (7), metering device is by the support that is used for fixing meter movement (31), shell (36), be used to show the digital dial plate (34) of the speed of a motor vehicle, transmission shaft (33) that is meshed with transfer connector (7) and indication indicator (32) are formed, described velocity measurement mechanisms is by utilizing and test the speed part (12) and be used for the gear assembly (13) of the rotating speed speed change that rubs is formed of the friction of wheel friction detection speed, gear assembly (13) one ends and the friction part (12) that tests the speed is meshed by gear, and its other end then is meshed by gear with transfer connector (7).
In technique scheme, described a kind of speed measuring device, described velocity measurement mechanisms also comprise be used for friction test the speed part (12) be pressed against on the wheel guarantee to test the speed friction part (12) and wheel can normally contact press spring (16).
In technique scheme, described a kind of metering device, described metering device comprise that also the mileage that is used to survey operating range shows meter and is used for odometer returned zero odometer zeroing knob (35).
Because the utility model all adopted mechanical hook-up in speed measuring device, so cost is lower, also for ease of maintenaince with maintenance, adopt the friction mode to test the speed then to have be quick on the draw, characteristic of accurate owing to be mechanical hook-up, so it installs fairly simple convenience.Simultaneously because odometer has been installed, the distance that the user can be calculated easily travel also can be calculated average velocity.
Below in conjunction with example the utility model is described further:
Fig. 1 is the structural representation of speed measuring device;
Fig. 2 is the dial plate synoptic diagram of metering device;
Fig. 3 is the side sectional view of metering device.
As Fig. 1, Fig. 2 and shown in Figure 3, velometer is by speed measuring device, transmitting device and metering device are formed, speed measuring device is geometrical clamp 11 then, shell 14 and velocity measurement mechanisms are formed, transmitting device is made up of transmission line and transfer connector 7, metering device is by the support 31 that is used for fixing meter movement, shell 36 is used to show the digital dial plate 34 of the speed of a motor vehicle, be used to survey the mileage demonstration meter of operating range, be used for odometer is returned zero odometer zeroing knob 35, the transmission shaft 33 that is meshed with transfer connector 7, indication indicator 32 and be used for the friction part 12 that tests the speed is pressed against on the wheel part 12 that tests the speed of guaranteeing to rub and forms with the spring 16 that presses that wheel can normally contact, velocity measurement mechanisms is by utilizing and test the speed part 12 and be used for the gear assembly 13 of friction rotating speed speed change is formed of the friction of wheel friction detection speed, test the speed part 12 of gear assembly 13 1 ends and friction is meshed by gear, and its other end then is meshed by gear with transfer connector 7.
After the installation, test the speed part 12 of friction is pressed spring 16 and is compressed.When vehicle ', wheel and friction part 12 friction of testing the speed, by gear assembly 13 speed changes after transfer connector 7 and transmission line pass to signal another transfer connector 7 at metering device place, drive instrument transmission shaft 33 and drive the present speed that indication indicator 32 shows vehicle again, at this moment odometer begins to have the records of distance by the log automatically.
