Abstract
The utility model relates to an automatic lubricating device for chains, which can carry out automatic lubrication for chains of chain driving vehicles such as motorcycles, bicycles, etc. and supply proper quantities of lubricating oil according to the vehicle speed and the road condition. The utility model is characterized in that the device is composed of a shell, a weight hammer, a spring, a valve and an oil storing pool, wherein, a vibration threshold is determined by factors such as the weight of the weight hammer, the elastic force of the spring, etc., and the shell is installed on a vehicle. Vibration can be generated while the vehicle is running, the vibration which is greater than the threshold causes the device to supply lubricating oil for chains, and the vibration which is smaller than the threshold causes the device not to supply lubricating oil. The basic oil supplying quantity can be changed through the changes of the weight hammer and the elastic force of the spring.
Description
The utility model relates to a kind of chain automatic lubricator, belongs to the vehicle lubrication system.
Some chain drive vehicles adopt manual intermittent oiling as the chain greasisng of bicycle, motorcycle etc. at present, not only bother, and lubrication effect are poor, chain and sprocket wheel quick abrasion.
The purpose of this utility model is to overcome the deficiency of manual intermittent oiling, and a kind of chain automatic lubricator is provided, and supplies with an amount of lubricant oil to chain automatically according to different situations.Supply with less lubricant oil when for example pavement behavior is better, supply with more lubricant oil when road conditions are relatively poor; Lubricant oil supply was more when speed was high, and the lubricant oil of supply was just less when speed was low, did not supply during parking.
The utility model mainly by housing, weight, valve, spring, hold oil sump and form.Housing is installed the place (in the motor cycle rear wheel swing arm) that can experience the vibration that causes because of Uneven road onboard, hold oil sump and install onboard, and the position is than housing height.When vehicle is advanced, owing to the road surface is not that housing is passed in the absolute smooth vibration that causes, as long as vibration is greater than vibration threshold values (this threshold value is determined jointly by factors such as spring force and weight weight), thereby the inertial force that weight produces will overcome the elastic force of spring makes opening of valves, and lubricant oil just drips to chain from the housing outflow and is lubricated.When speed of a motor vehicle increase or road conditions are relatively poor, the vibration aggravation, bigger greater than the generation of vibration probability of threshold values, so supply with more lubricant oil.On the contrary, supply with less lubricant oil when less or road conditions are better when the speed of a motor vehicle, and when stopping because the active force of spring is closed valve, just fuel cut-off.Change the weight of weight or the factors such as elastic force of spring and can change vibration threshold, thereby change basic fuel delivery.
Come the utility model is elaborated below in conjunction with accompanying drawing.
Fig. 1 is embodiment 1 a structural representation.
Fig. 2 is embodiment 2 a structural representation.
Embodiment 1:
See Fig. 1.Housing 1 and to hold oil sump 6 fixing onboard, and the position of holding oil sump 6 is than housing 1 height.The filler opening of housing 1 top with hold oil sump 6 and link to each other by oil pipe 5.Weight 2, spring 3 and sealing awl 4 are arranged in the housing 1.Sealing awl 4 is formed a valve with the filler opening on the housing 1.During stationary vehicle, weight 2 withstands sealing awl 4 under the effect of spring 3, make it to seal the filler opening on the housing 1, and valve promptly is closed, and the lubricant oil that holds in the oil sump 6 can not enter in the housing 1, therefore not to the chain supplying lubricating oil.When vehicle driving, because Uneven road causes vibration, fixing housing 1 onboard is up-down vibration also, makes weight 2 produce an inertial force.The elastic force of the weight of weight 2 and spring 3 can be determined a vibration threshold.Can make weight 2 produce the elastic force that enough big inertial force overcomes spring 3 greater than the vibration of threshold value moves down, at this moment sealing awl 4 moves down thereupon, thereby leave the filler opening on the housing 1, valve promptly is unlocked, hold lubricant oil in the oil sump 6 and just enter housing 1 and flow out, drip on the chain from the oil outlet of housing 1 below.Can not make weight 2 produce the elastic force that enough big inertial force overcomes spring 3 less than the vibration of threshold value and make opening of valves, so the lubricant oil stop supplies.When very fast the or road conditions of the speed of a motor vehicle are relatively poor, bigger greater than the generation of vibration probability of threshold value, so fuel feeding is more.Otherwise then fuel feeding is less.
Embodiment 2:
See Fig. 2.The filler opening of housing 8 tops by oil pipe 14 with hold oil sump 15 and link to each other, there are spring 9 and steel ball 10 in the oil outlet place of below, steel ball 10 is formed a valve with oil outlet.There is lever 12 steel ball 10 tops, and lever 12 1 ends are pushed down by spring 7, and a weight 13 is arranged on the other end, and lever 12 can rotate around bearing pin 11.Vibration threshold is determined jointly by the elastic force of spring 7 and spring 9, the weight of weight 13 and the factors such as length of lever 12.Vibration is during less than threshold value, and the inertial force deficiency that weight 13 produces is so that lever 12 overcomes the elastic force of spring 7 rotates clockwise around bearing pin 11, and steel ball 10 is pressed on the oil outlet by lever 12, and promptly valve is closed, and device is not to the chain fuel feeding at this moment.Vibration is during greater than threshold value, the elastic force that the inertial force that weight 13 produces is enough to make lever 12 overcome spring 7 rotates clockwise around bearing pin 11, steel ball 10 rises under the effect of spring 9, no longer seal oil outlet, be that valve is unlocked, this moment, lubricant oil flowed out from the oil outlet of housing 8, dripped on the chain to be lubricated.Fuel feeding is more during the fast or road conditions difference of the speed of a motor vehicle, and fuel feeding was less when the slow or road conditions of the speed of a motor vehicle were good, and fuel feeding not during parking is consistent with actual demand.
Claims (2)
